Neoclassical Architecture c. 1780-1850

There are four main variations or phases of Neoclassicism; these are
best described by William Pierson, Jr., in American Buildings and their
Architects, vol. I: Colonial and Neoclassic Architecture:

Federalist: Especially common in New England; a traditionalist approach to classicism,
heavily influenced by English models. Charles Bulfinch, Samuel MacIntyre.Federalist Style

Idealist: An intellectual and moral approach to classicism, at first linked to
Roman models. Symbolic and associational values stressed, with a goal of
creating an expressive, "speaking architecture." Best example:
Thomas Jefferson.Jefferson's Idealist Style

Rationalist: Emphasized structure and classical building techniques, such as stone
vaulting and domes. Best example: Benjamin Latrobe.

Greek Revival (1818-1850)

values. Permeated all levels of building.The Greek Revival Style
